The present invention has among its objects to provide a gas burner ofsuch formandconstruc: tion that gas may be discharged therefrom inspaced parallel. streams; that upon beingpqsb.

tioned in an air supply conduit: theconduitwill be divided by the burnerinto a plurality of .parallel passages for the flow of air from theconduit; that the burner may be readily removed from said conduit; thatoverheating of thefgas supplied to. the burner may be. prevented, andwithal toprovide a burner which shall be rela tively simple. inconstruction and otherwise. well adapted for its intended purpose. T

The various features of novelty and invention will be more fullydescribed in connection with the accompanying drawings forming part ofthis specification wherein the preferred. formof burn} er constructionis shown. and wherein,;

- Referring to Figs. 1 and 6,"nu-meral 10 indi'-' cates a vertical endwall, 11 is a, side wall and 12 the roof of a furnace tobe fired.Indicated at Ais a rectangular air-supply-oonduit' of sub-f stan-tiallythe same width as the furnace tobe fired, this conduit being shown asiomied-by an: extension of the furnace 'roof 12, and "side walls 13 and14 and a floor or bottom wall '15. Generally speaking, thearrangementthus fardescribed is similarto thatshown in Fig. 1 of-Pat entNo. 1,900,432.

The burner as a whole is generally indicated at B and is supported on acarriage C supported on transversely extending rails 16, the carriagebeing below the bottom wall or floor 15 of the conduit A as is clearlyshown in Fig. 1. The purpose of the carriage is to permit the burner tobe moved laterally out of the conduit for inspection and repairs. Aportion of the conduit side wall 13 is supported on the carriage as isclearly shown in Fig. 6 and hence it is a simple matter to withdraw theburner from the conduit as will be readily appreciated. Sand seals 17form a suitable closure-between the top of the carriage Q anilinenderside o th said floor Asis: clearlyshowndn Fig; 6, the burner com- 7i s aplu a iwc u ight o s ra d in laterally spaced. relation 'to. formindividual .5 passages 20 througlrwhichthe air'irom the conduit A mayflow toward the furnace for support ing combustion of the gas dischargedfrom the burner.. TIhesaid bodiesare of va substantial lengthlongitudinallyoi the conduitA (Fig. 1) 1 0 and; are of substantiallythe1 same height as the cpnduiugand;as..will1more .fully appear herein- Iiisi erleeh rov ded wi h a row of g 1 zies.,.;' H I Thefs'aidfbodiesl19. are individuallyand remov ably supported onani elongate,base"2l'secured to the 'top or thecarri'ag'fC'. {To this endthe're aresecured to 'thejbase 21 individual stools 22' havipgup'righti flanges asbetween which; is con-. fined. a reiractorybedl, the stools beingchainbered for p rp ses. presently appearing,

a H Eacli bodyila.isprferablymade up of a series-offltiles.26}bflthe'shape'shown 'in Fig. 4', and the bottomine'mberofeach body maybe a simple spacerv block 25.. Each'tilehas a nozzleZ'T-and anfoblongfaperture or 'sl'ot' 28. 'W'hen the tiles areassembledin"verticalseries' to make up the body l asshowrr in Fig: 2,the'slots constitute.

what maybe termed a-- tunnel." v a Gas is supplied't'o thenozzles 2'7 byindividual nipples 129*Whl8hproject into the receiving end of thenczzlesas. is. clearly shown Figs; 2 and 3. The nipples project from a gas pipe30;-which projects upwardly from an individual stool 22, thel-ower endoithe pipe being indirect com- U munication with a gas. chamber 31formed in the stool, said chamber being; in direct communication.withfa. maingas chamber 32 formed in the. 7 base 21 as is clearlyshownfin'Fig. 5. Gas is de-' livere'd' to, thefmain gas chamber 32'by amain pp ip p If the' gas'fiowing through-the pipes 30 becomesoverheated, it will break-down with the libe'raQ tion' ofcarbonconsequent clogging of. the pipes and the nipples 29. To preventsuch overheating, the pipes 30 are water cooled. To this end each pipeis surrounded by a hollow post or water jacket 34 to which water isdelivered by a pipe 35 which has its discharge terminal. near the top ofthe jacket as is shown in Fig. 2and end is closed by being welded to thepipes 30, 35

' i and 39 at a point above the stool 22. It .will be noted that thenipples 29 extend through and project a substantial distance beyond theadjacent side wall of the jacket 34.

In transverse cross section, the jacketis' as wide as the slot 28 in thetile 26 but in transverse length it is the shorter bynthe distance thata nipple 29 projects beyond the wall of the jacket I I as is clearlyshown in Fig. 3. Byreason of .this

construction it is a simple matter to position the tiles 26 on the postsas shown in Fig.2. Thus referring to Fig. 3, it will be understood thatthe space 42 is suificient to' permit the tile to' be moved toward'theright a sufiicient distance to disengage thenipple 29 from the receivingend of the nozzle 27. After a tile'h'as been placed on itspost 34, thespace 'or gap 42 will be filled with cement, thus keying the tileson'the post or jacket 34.

Since each of the bodies 19 is supported ona stool 22 and since thesestools are detachably secured to the base 21 and since the burner as awhole may be readily withdrawn from the conduit A, it will'be readilyappreciated that it is a simple matter to replace anyparticular'bodywith a new unit in case necessity demands.

i It is desired that air from the conduit'A shall flow between thebodies 19 in stream-line flow and to this end the individual ,tiles 26making up the body are of stream-line form as is clearly shown in Fig.4. It is also desired that the gas shall be discharged from the nozzles27 in stream-line flow and to this endthe passages which constitute thenozzles are of gradually diverging or stream-line form as is clearlyshown in Figs. 2 and 3. From the foregoing description it will bereadily appreciated that there will be alternating sheets of air andgas. flowing into the Ifurnace. Ordinarily the air and gas will flowfrom the passages ;20 and nozzles 27- at equal and relatively lowvelocities in order that mixing of the air and gas may proceedrelatively slowly with the consequent construction of a relatively longflame;

What I claim is: 1. In a gas burner, an elongate base having a gaschamber, a plurality of stools each having a gas chamber in directcommunication with the gas chamber in said base, a gas pipe supported.

cent wall of each post, and means associated with said stools and basefor supplying cooling fluid to said posts.

2. An article of manufacture for a gas burner comprising an elongatebody which at one end and for a substantial portion of its length iscircular in cross section and which intermediate its ends on a plane atright angles to the axis of the circular portion is rectangular in crosssection andwhich remotefrom'the circular portion of the body is providedwith a transversely extending aperture, said circular portion beingaxially apertured, the two apertures being in communication.

3. In a gas burner, a supporting base, a plurality of elongate bodiessupported on said base in upright spaced .relation to form passagesthrough which air may flow, each of said bodies being longitudinallyapertured, a hollow post in each of said apertures, a series of nozzlesprojecting in spaced relation from one longitudinal edge' of each ofsaid bodies, and means housed-by the posts for supplying fuel gas tosaid'noz'z'les.

; 4.=In a gas burner, the combination of a pluralityof elongate-bodieseach having a transverse" aperture therethrough adjacent one end and alongitudinal aperture extending from said transverse apertureto'theother end of the body, said bodies being mounted side by side withtheir transverse apertures in alinement, and a gas supply pipe extendingthrough the transverse'apertures'an'd cou'pled to the adjacent end ofeach of the longitudinal apertures for'supplying gasthereto. H V

,5. In a' gas burner, the combinationrof an elongate body having atransverse oblong aperture and a longitudinal aperture extending fromsaid transverseapertureto the other end of the body, and a gas supplypipe extending into said transverse aperture and having a nippleextending into .thefadjacent end of the longitudinal aperture,'thelength of the nipple plus the ex ternal diameter of the gas pipe beingless than the'major dimension of the oblong aperture.

' 6. Ina gas burner, the combination of an elongate body having atransverse oblong aperture and a longitudi'nal aperture extending fromsaid transverse aperture to the other end of the body, atubeprojectingintothe oblong aperture and susbtantially filling thelatter between its sides, agassupply pipe housed by saidtube, andmeans-coupling the gas pipe to the adjacent end of the longitudinalaperture.

'7. Ina gas burner, a plurality of elongate bodies arranged in spacedparallel relation to form passages through which air may flow, each ofsaid bodies being longitudinally apertured, a hollow post ineach of saidapertures, a series of nozzles projecting in spaced relation from onelongitudinal. edge of each of said bodies, and means housed by the postsfor supplying fuel to said nozzles.
